Okla. Stat. tit. 12, § 2508
A person or entity has a privilege, which may be claimed by him, his agent or employee, to refuse to disclose and to prevent other persons from disclosing a trade secret owned by him, if the allowance of the privilege will not tend to conceal fraud or otherwise work injustice. If disclosure is directed, the court shall take such protective measures as the interest of the holder of the privilege, of the parties and of justice require.
